Today, Proculus smart industrial tablets are widely known in business. Coupled with the growing need for smart shopping malls, Android industrial tablets can be better connected to mobile terminals, and its advantages will gradually emerge. This will also bring great convenience and practicality for the intelligent management of the industrial site.

When it comes to smartphone screens, there are two predominant technologies—the traditional LCD panel, and the newer AMOLED display. Most phones still use LCD screens, as the tech is more cost-effective due to its longstanding reign as the primary display type in TVs, smartphones, and tablets.AMOLED screens are more energy-efficient, and offer higher contrast levels and deeper blacks.

But in recent years, AMOLED screens are starting to take over as the technology matures and becomes cheaper and more reliable. The advantage of an AMOLED display is that each pixel emits its own light, meaning a separate backlight is not required. As a result, when compared to LCD displays, AMOLED screens are more energy-efficient, offer higher contrast levels and deeper blacks, but are more susceptible to screen burn-in.

While most smartphone manufacturers market the display resolution in their devices, not many advertise whether they are AMOLED or LCD. And with Apple recently rumored to be making the switch from LCD to AMOLED in its iPhone 8, there will surely be some confusion on this front. So if you"re curious as to which display technology your smartphone uses, I"ll show you how to find out below.

Secret codes, hidden menus, identification numbers — although it might sound like we’re going to discuss espionage, we’re actually going to talk about how to test Android devices.

Aftermarket Android and Apple iOS devices should be tested before they’re offered for sale to ensure that they’re fully functional. You can enter hardware test codes on Android phones to find key information about everything from how well a touch screen works to the current battery status.

There’s a wide array of what you can manually test on an Android smartphone. Unlike Apple iPhones, Android users have access to many test modes. These permissions make it much easier to perform troubleshooting in case you notice a device is having a particular issue.

Hardware test codes provide detailed technical information about a phone and its performance. For example, you can view information about the functioning of any cameras, audio hardware, and the GPS.

Whether you’re testing a Samsung Galaxy or a Google Pixel device, the way to enter Android hardware test codes is through the phone’s dialer. Simply open the phone app and navigate to the keypad to tap in any of the codes detailed below.

It’s important to note that not all Android secret codes work across all devices. If a code doesn’t work, double-check to make sure you’ve entered it correctly. If the secret code still doesn’t bring up a hidden menu, it’s probably because that code isn’t enabled on that particular device.

Manufacturers create hardware test codes as a way to perform device quality checks and performance testing. These codes can also come in handy for individual users, such as when you’re checking a phone’s status to sell it.

Android hardware test codes reveal details about a device’s LCD display, vibration sensors, Bluetooth functions, and much more. Check out the following codes to find key technical information about an Android device’s hardware.

When you enter *#0*# into the phone’s dialer, the device enters service mode and brings up a diagnostics menu. From this screen, you can view and run multiple diagnostics to test device hardware like buttons, sensors, and cameras. You can also check colors from this test menu to pinpoint if there are any damaged pixels on the touch screen.

Enter the code *#*#4636#*#* on the keypad to display information about your current service carrier. This field test code should display items like the phone number, IMEI number, and app usage history. This Android service menu also provides information about the data network connection and Wi-Fi status.

The secret code *#*#0*#*#* tests the smartphone’s LCD display screen. Dead and stuck pixels are a common problem. When small color pigments on a screen break, they create a black spot called a dead pixel. If a colored pixel on the screen refuses to change colors, it’s called a stuck pixel.

The screen will run through blue, red, black, and green during the LCD display test. If you observe any pixels on the screen, you know your display has a problem. All LCD color tests, except for black, can be exited by pressing the back button. Push the phone’s power button to exit the black screen test.

Input *#*#2664#*#* into the dialer to test the touch screen’s performance. This test is useful if you’ve noticed your touch isn’t functioning as it should. It’s also great for testing a phone for resale because you want to make sure there aren’t any dead zones on the touch screen. The touch test can also analyze multitouch, 3D touch, and other vital touch points.

Screenshots, selfies, QR codes — smartphones have multiple cameras with a variety of functions. Most people use their phone’s camera every day. You can display the phone’s camera information with the code *#*#34971539#*#to ensure they are all working correctly.

Entering the GPS test code *#*#1472365#*#* allows you to run a quick test to ensure the GPS is accurate. You can make easy adjustments in the location settings if the phone can’t find a location or shows an inaccurate location. According to HTC, make sure the location is turned on and then tap “high accuracy” in the location settings to improve GPS accuracy.

Run an audio test with one of the two codes above to test the functionality of a phone’s speakers. If sound is played clearly and the volume is adjustable, the phone has passed the test. If one or more of the speakers struggle to emit sound, there’s some troubleshooting that’ll need to happen.

A phone’s vibration is often just as important as audio, as some people rely on it for notifications, messages, and calls. The Android test code *#*#0842#*#* tests a device’s vibration and backlight performance. A phone’s backlight is the light source that runs behind the LCD display so users can see what’s being projected onto the screen.

Enter the secret code *#*#0588#*#* into the Android mobile device to test the proximity sensor chip. Fixes are as simple as cleaning dust and dirt from the sensor to as complex as recalibrating the proximity sensor with an app from the Google Play Store.

Working Bluetooth is essential to wirelessly connect phones to other devices, like headphones or portable speakers. Tap the Bluetooth test code *#*#232331#*#* into the phone’s dialer to test the wireless connection.

Depending on what technical info you need to gather or test, you may find some of these other secret codes to be as useful as the ones mentioned.Display build time [*#*#44336#*#*]

You can use secret codes to access an Android device’s built-in diagnostic tools to gather info, but this method can be time-consuming since you have to run tests individually. The best way to present device info when selling a phone is to use third-party certification that includes a history report about the phone. Third-party certification ensures the honesty and validity of a device’s condition.

From secret codes that enable a direct power off to backing up media files, there are a lot of Android secret codes to take advantage of when testing or customizing a phone. However, individually testing multiple Android devices is extremely time-consuming; problems can be missed if you don’t run a thorough, all-inclusive test on each phone. If you don’t have time or access to a phone’s diagnostics, avoid costly hidden problems with a Complete Device History Report through Phonecheck for about the cost of a cup of coffee.

Do you know you can use hidden secret codes to run the hardware test in an Android smartphone? These sets of codes are used to diagnose and test both hardware and software of your android smartphones. So, what actually is the secret codes? How do they look like? Who can use such secret codes? And How to use such codes to run the test on your android devices? Let’s Discuss.

Secret Code is the sets of special commands or the instruction that is executed to perform a specific task within your android devices. These codes are used during the hardware and software test on Android. Secret Codes also helps us to enable and disable lots of hidden setting. With the help of such code, you can easily check the phone’s hardware and software. Similarly, you can get information about the phone, details of the apps you have been using, battery information and much more. The main purpose of using such code is to check if the devices are functioning well or not.

Secret Codes are the hidden features in Android devices so everyone is not familiar with such codes. Such codes are especially used by the experienced user. One can use such codes if they are strong technically. Misuse of such information can lead to loss of data or hardware damage. Hence, it is recommended to use if you are technically good.

You don’t need any application to run the hardware test in the Android smartphone. Just pull up the call dialer and press the correct instruction. The phone will automatically show the information as soon as the user finishes typing the secret code.

Here is the screenshot from the hardware test of Android smartphones. The code used for testing hardware is *#*#4636#*#*. The screenshots below show information about the battery, usage of the phone’s application and information about the phone.

The most common issues of Android screens are dead and stuck pixels. Dead pixels occurs when small color pigments of your screen gets busted, resulting to a black spot on your screen, while stuck pixels are color pigments of the display that are frozen, unable to change to other colors like it normally should. These issues can easily be avoided if you can detect it while the problem is still not that severe. That"s why testing your LCD display is outright important and needs to be done frequently to avoid any issues from worsening.

Given that the touchscreen display is the way people interact with their smartphones — from looking at photos to watching videos, from dialing numbers to texting — it was only a matter of time before DXOMARK turned its attention to display performance quality. Well, that time has come. DXOMARK has installed a brand-new, dedicated state-of-the-art test laboratory and hired a team of experts who have been hard at work evaluating display performance since late spring.

Although our DXOMARK Display protocol includes the same kinds of measurements available on other sites — that is, performed on text and single images processed using the device’s gallery app — there are two very important and unique aspects of our new protocol that set it apart from the typical manufacturer’s quality assurance process and from other display quality review sites. The first is that DXOMARK tests displays under real-world conditions. Those manufacturers who calibrate smartphone displays as part of their end-of-line tests do so in a dark room (no ambient light), with the testing device pressed against the display.

In the real world, of course, users do not press their displays right up against their eyes, but hold them several centimeters/inches away, which means that ambient lighting has an impact on how easily people can see the contents on their display. Further, people look at their displays in all kinds of lighting conditions — dark night, indoors, in shade, in sunlight. So DXOMARK engineers evaluate display brightness, contrast, and color both objectively and perceptually by performing tests with the display exposed to different ambient lighting levels.

The second way in which the DXOMARK protocol is unique is that it is the first to test the dynamicattributes of a smartphone’s touchscreen display. This means two things: first, DXOMARK evaluates how well the display renders moving content such as videos and games — in other words, the content that is handled by the device’s default video (or browsing) app, which uses different algorithms to process brightness, color, and so on. Among other things, our engineers check for frame drops and stutter, problems with frame-to-frame image quality, motion blur, and for color and other rendering issues. Second, DXOMARK evaluates the display’s touchscreen functionality, testing its responsiveness, touch accuracy, and smoothness.

(Please note, by the way, that although we are premiering this new protocol by applying it first to smartphones, we plan on testing other kind of displays — tablets, monitors, televisions, etc.— in the future.)

In preparation for this new protocol, DXOMARK installed in its Paris headquarters a new state-of-the-art laboratory entirely dedicated to display testing, and equipped it with the latest testing instruments, including spectroradiometers, imaging colorimeters, conoscopes, high-end DSLRs and professional reference monitors, among other tools. Furthermore, DXOMARK recruited a team of expert scientists and engineers to perfect testing methodologies and to conduct tests.

But that’s not all. The Display team designed and built a brand-new testing chamber, called the Display Bench, to facilitate testing automation and to ensure that all devices are tested under the exact same conditions. The Display Bench includes adjustable mounts for testing tools and for the smartphone display being tested, LED lighting arrays to imitate all kinds of lighting types and brightness levels, and lux meters.

After the test device and the testing tool are attached to their respective mounts, the Display Bench is sealed against any external light sources, and then our experts use a computer console located outside the chamber to take all test shots, as well as to control the servomotors used to change the shooting distances, and to control the lighting arrays that recreate lighting conditions ranging from near-pitch darkness to bright daylight (above 30,000 lux).

Before we go further, it may be helpful to briefly describe how a typical display is put together. While LCD (“liquid crystal display”) smartphones are still in widespread use, many newer high-end smartphones have OLED (“organic light-emitting diode”) displays that are composed of multiple layers of different materials — glass with an underlying pixel array, a thin film of transistors (TFT) to drive each sub-pixel, a touch panel to enable touch control, and specialized coatings to reduce reflection and other problems. Both LCD and OLED screens are of course connected to their smartphone’s processor and battery.

Now let’s return to the DXOMARK protocol. But before we get into the specifics of the attributes we measure, it’s important to reiterate that all DXOMARK testing is based on the end-user experience. So when DXOMARK engineers were designing the new protocol, they thoroughly considered the ways in which and under what conditions people typically use their displays in real life. The end result of that study is an array of tests designed around eight specific (and largely self-explanatory) use cases:

Interactivity is another big consideration (and not just for gamers). How responsive is the touchscreen? When you scroll and when you pinch to zoom in or out, does the display keep up with your commands? Do you end up where you want to be, or do you have to keep fiddling to get to the right place in a text or on a web page, or to obtain the right amount of magnification?

Gamma vs ambient lighting: Gamma is the relationship between the numerical value of a pixel in an image file and the brightness of that pixel when viewed on a screen.

From an end-user’s point of view, what tends to be the most important consideration about color is how faithfully the hues on the display match what the user sees in real life. In addition to manufacturers’ design choices and tuning, different lighting conditions, reflectance, and angle viewing can significantly impact how well users perceive a display’s color rendering. DXOMARK tests within both the sRGB (standard red, blue, green) and the newer DCI-P3 (digital cinema intiatives – protocol 3) color spaces (also known as gamuts) for the following characteristics:

Unlike a smartphone’s default gallery app, which handles one image at a time, a smartphone video or browser app has to process many images or frames per second, which poses different kinds of challenges. The Display protocol tests for some of the same kinds of image quality attributes for video content as it does for still images — brightness, contrast, gamma, and color (including skin tone rendering).

How well does the display handle moving content? In practical terms, this means that DXOMARK tests for frame drops and stutter, motion blur, and video playback reactivity.

All end-users, not just gamers, care about how responsive, accurate, and smooth the touchscreen is. Among other considerations, our tests determine if the touchscreen avoid under- or overshoots when zooming, and if it scrolls quickly and smoothly — in other words, the DXOMARK protocol evaluates a display’s touch accuracy and smoothness.

Notch: Manufacturers have to find a place to put front-facing features (for example, cameras and speakers). Rather than reduce the overall size of the screen by putting these components outside of the screen area, many models now include them right on the display. DXOMARK measures not just how much of the display area is taken up with the notch, but also how intrusive it is when it comes to viewing or interacting with content.

Our reviews will largely follow the same format as for our other protocols (sensors, lenses, smartphone rear cameras, selfie cams, audio): An introduction, essential specifications, test summary, in-depth analyses per attribute (with occasional dives into sub-attributes), conclusion, and pro & con bullet points. We will also publish one or more articles that will provide much greater detail about various aspects of our Display protocol, including more information about our testing setup and the equipment we use to evaluate specific attributes, so stay tuned!
